Remember Project Shield from CES and before? The Inquirer has managed to get their hands on an actual console at the Game Developers Conference and played a bit of Need For Speed streamed from a PC onto the Shield. Project Shield its self is a Tegra 4 powered controller running Android 4.2 with a 5" 720p display attached and wireless connectivity. The actual game is streamed wireless from a PC with a Kepler GPU via the Tegrazone application, so the real performance limit occurs from latency, similar to the company once known as Onlive. While The Inq was not quite ready to toss their money at Project Shield, but it was close.
"CHIP DESIGNER Nvidia caused something of a stir at CES when it announced the Project Shield handheld games console, and with its launch nearing, the firm is letting people try its first own-brand game console, which we managed to get our hands on at this week's GDC gaming conference in San Francisco."

Tim did a post on cheap 27" IPS 1440p monitors from Monoprice within the opening days of the calendar year. These panels are derivative of the type you would see on Dell Ultrasharp or Apple Cinema Displays. We say derivative because LCD panel manufacturing is very imprecise: completed panels get graded, bin-sorted, and sold to bidders. A panel which does not grade high enough for Dell, Apple, HP, and other professional companies is probably still a perfectly good panel and suitable for other bidders. Monoprice is putting their branding on one of those bidders and selling it for under $400, about a third of the cost of the A+-sorted panels.
And they're gone.
Now, almost three months later, Monoprice has caught up and will start shipping the new batch as early as tomorrow. How long that will last, who knows? If you wish to have a high end monitor on the cheap, you will probably want to run and not walk.
The Monoprice CrystalPro WQHD monitor is available for $390.60. Monoprice advertises the display to be perfect for Eyefinity setups... except that it is limited to one per customer. Oh well, troll well.

Tagged: arm, calxeda, Boston Viridis
Perhaps the most telling part of AnandTech's review of the Calxeda Boston Viridis server was the statement that "It's a Cluster, Not a Server" as that paints a different picture of the appliance in many tech's heads. When you first open the chassis you are greeted by 24 2.5” SATA drive bays and a very non-standard looking motherboard full of PCIe slots, each of which can hold a EnergyCard which consists of four quad-core ARM SoCs, each with one DIMM slot and 4 SATA ports with the theoretical limit being 4096 nodes interconnected by physical, distributed layer-2 switches not virtualized switches which use CPU cycles. Check out the results of AnandTech's virtual machine testing and a deeper look at the architecture of the cluster in the full article.
"ARM based servers hold the promise of extremely low power and excellent performance per Watt ratios. It's theoretically possible to place an incredible number of servers into a single rack; there are already implementations with as many as 1000 ARM servers in one rack (48 server nodes in a 2U chassis). What's more, all of those nodes consume less than 5KW combined (or around 5W per quad-core ARM node). But whenever a new technology is hyped, it's important to remain objective. The media loves to rave about new trends and people like reading about "some new thing"; however, at the end of the day the system administrator has to keep his IT services working and convince his boss to invest in new technologies."

Tagged: spintronics, racetrack, pram, molybdenum, micron, memristor, IBM, hp, graphene, flash
Over the past several years we have seen actual production of phase change memory from Micron, though no benchmarks yet, transistors whose resistance can be altered to be used as non-volatile storage which HP has dubbed Memristors and IBM's Spintronic Racetrack Memory; all of which claim to be the replacement for NAND. There is no question we need a new type of flash, preferably non-volatile, as it is likely that there will be a limit on effective speed and density reached with traditional NAND. It is also true that the path to our current flash technology is littered with the carcasses of failed technology standards, whether RAMBUS is willing to admit it or not.
Now there is more details available on yet another possible contender based on molybdenum disulfide which sports a charge-trapping layer to make it non-volatile. The Register was told that by layering MoS2 between layers of graphene they get a NAND cell smaller than traditional cells but unfortunately there was no report of the speed of these cells. We may soon be living in interesting times, with process shrunk traditional flash and these four technologies competing for market share. You can bet that they will not be compatible and that each will likely spawn their own breeds of controllers and make purchasing SSDs and other flash storage devices much more complicated, at least until one standard can claim victory over the others.
"A Swiss government research lab has reinvented flash memory using graphene and molybdenite in a way that should be faster, scale smaller, use less energy and yet more flexible than boring old NAND.
Molybdenite is MoS2, molybdenum disulfide, which is similar to graphite and also has a lubricating effect. Atomically it is a layer of molybdenum atoms between top and bottom layers of sulfide atoms. It is a semiconductor and can be used to create transistor."

Tagged: windows 8, Blue, windows blue
It was only a matter of time before Windows Blue was leaked, like just about every other version of the operating system in recent memory. Internally, Blue is a transition for Microsoft into an annual release schedule for Windows products; externally, Blue is the first feature-release for Windows.
Yes, Sean Bean, win'ders has come.
Zac from WinBeta, embed above, got hold of the operating system, apparently leaked today, and played around with the changes for all of YouTube to see.
New split-screen App options. (Unclear whether multi-monitor app support is fixed)
- Minor clarifications for user instruction.
- New tile sizes.
- Swipe up from Start Screen to access list of apps.
- More personalization options.
- Picture frame mode.
- New App: Calculator.
- New App: Alarm.
- New App: Sound Recorder.
- New App: Movie Moments... apparently a new, confidential, video editing application.
- Internet Explorer updated to version 11.
Personally, despite sticking with Windows 7 for political reasons, the new App options seem like they would be the most engaging feature for Windows Blue. For being such a core segment of the "modern" Windows experience, apps are surprisingly annoying to manage as they currently exist on Windows 8. If you have two or more monitors then you are probably having a nightmare with anything outside of Windows 8's desktop mode.
We now know that app support is being looked at, so there is some hope that multiple monitor users will be considered too.

Tagged: bioshock infinite
So The New York Times wrote an editorial about Irrational Games to lead-off the upcoming release of Bioshock: Infinite. The piece is fairly typical, describing co-founder Ken Levine along with the very nondescript studios nestled away within Quincy, Massachusetts. The piece focused on how much the team cares for their game Bioshock: Infinite...
... and then it speculated a quantity for how much they cared, citing unnamed analysts.
Of course this could not help but become a minor controversy like just about everything else surrounding Bioshock: Infinite these days. The piece reported a budget that was "upward of $100 million", excluding marketing which could add an extra $100 million to that figure. Naturally, $200 million dollar stories began to spring up online.
200 million for Infinite? Did someone send some checks to the wrong address? #unnamedanalyst
— Ken Levine (@IGLevine) March 22, 2013
This prompted a tweet-based response from Ken Levine, because who needs a PR firm when you got Twitter? Anyway, the man has a sarcastic sense of humor and this is no different.
While funny, this is not actually a denial. Games are quite expensive to produce and can be very expensive to market. Sure, the NYT figure is still probably an overshoot even if you were to zealously round up, but I would still hesitate to mock.

AMD is trying to fill a gap in their product line between the less than $200 HD 7850 and the ~$120 HD 7770 with a $150 card, the HD 7790. The naming scheme implies two GPUs but this is not the case, it is a single Bonaire GCN chip with 896 stream processors, 56 texture units and an impressive fill rate of up to 1.79 TFLOPS thanks to some optimization of the GCN architecture. It has 1GB of GDDR5 at 6GHz effective and a CPU speed dependent on the model, in [H]ard|OCP's case the ASUS Radeon HD 7790 DirectCU II OC runs at 1.075GHz. [H] passed it a Silver Award for being a vast improvement over the 7770 and good competition for the GTX 650 Ti but feel the card does need to be faster.
This card also makes an appearance on our front page, with a lot of Frame Rating charts so you can see not only the raw FPS data you are used to, but also an indept look at how the game is going to 'feel' while you play.
"AMD is launching the Radeon HD 7790 today. This new video card should give the sub-$200 video card segment a kick in the pants. Will it provide enough performance for today's latest games at $149? We will find out, testing the new ASUS Radeon HD 7790 DirectCU II OC with no less than six of today's hottest games."

Gaming headsets are about more than just decent 40mm drivers which provide decent sound. We have seen virtual and physical 5.1 headphones, a wide variety of earcup and headband materials and occasionally vibration features so that when the artillery starts falling you can feel as well as hear it. AZiO's new Levetron GH808 sports that latter feature with a 30mm vibration driver which will indeed rattle your brains. HiTech Legion liked the volume control wheel integral to the headset but they would have liked one to control the vibration as well instead of it being all or nothing. At an MSRP of $55 they are not a major investment if you are curious about how this headset would feel.
"AZiO’s Levetron GH808 is a USB headset designed for gaming. The Levetron GH808 headset is plug-and-play, only requiring USB port on a Windows or Mac OS X system to use. Optional software can be downloaded from AZiO’s website, providing control of the GH808’s features from the desktop. Equipped with 40mm neodymium drivers and an additional 30mm “vibration” driver, the AZiO Levetron GH808 brings pulse-pounding excitement straight to gamers’ ears. Should you need to chat with your online buddies while playing, a unidirectional microphone can be pulled out from the left ear cup. The AZiO GH808 also includes a volume control knob as well as a toggle switch for enabling or disabling the bass enhancement feature."

FanlessTech recently spotted two new fan-less and small form factor cases from Akasa ahead of the official launch. The Akasa Galileo and Akasa Newton are compatible with thin Mini-ITX and Intel's Next Unit of Computing (NUC) motherboards respectively.
Both cases are constructed of aluminum, have VESA mounting holes, and double as a fan-less heatsink for your components. The Galileo is 37mm thick and can cool processors rated up to a 35W TDP. The Newton is a small case with fins around the sides to increase surface area (for better cooling capability), and aesthetic flair.
According to Fanless Tech, the two PC cases will be officially unveiled at Computex in Taipei, Taiwan this summer. There is no word on pricing or when they will be available for purchase, however.

Tagged: Vengeance K70, corsair, cherry mx red
FREMONT, California — March 21, 2013 — Corsair, a worldwide designer of high-performance PC gaming peripherals, today announced the Vengeance K70 fully mechanical gaming keyboard.
The new Vengeance K70 gaming keyboard is built on a rugged, brushed, aluminum chassis and features highly responsive Cherry MX Red mechanical switches under every key. The high performance switches combined with the keyboard's 100% anti-ghosted matrix, 20-key rollover and 1000Hz reporting rate provide fast, accurate input for gaming.
The Vengeance K70 gaming keyboards are available in two color schemes: silver aluminum with blue backlighting, and anodized black with deep red backlighting. Overall backlighting can be adjusted to four levels of intensity and each key is individually backlit, enabling the lighting for each key to be independently enabled or disabled. The key-by-key lighting customization allows users to highlight just the keys they need to emphasize and then save the setting directly to the K70's onboard memory. In addition, the Vengeance K70 comes with alternate colored, contoured keycaps for the WASD and 1-6 keycaps to allow additional customization.
"When we launched the Vengeance K60, customers loved the look and quality, but some wanted a backlit version," said Ruben Mookerjee, VP and General Manager of the Peripherals Business Unit at Corsair. "In typical Corsair fashion, we over-delivered and created Vengeance K70 with key-by-key backlighting, mechanical switches on every key, and two color schemes."
The Vengeance K70 also features dedicated multimedia controls to allow users to play, stop, pause, skip tracks and adjust volume. An extra USB connector is provided for attaching to USB devices such as a Vengeance gaming mouse or headset. A removeable soft-touch wrist rest provides comfort for long gaming or typing sessions.
See Vengeance K70 at PAX East from March 22-24
The Vengeance K70 keyboard will make its public debut at Corsair's booth at PAX East in Boston from March 22-24. Corsair is located in booth 1062.
Pricing and Availability
The Corsair Vengeance K70 will be available in April at suggested price of $129.99.

It might be worth waiting until next month if you are going to be building a low cost AMD based system as prices on the A8-5600K, FX-8320, FX-6300 and FX-4300 will be dropping in April. You can also expect to see the A4-4000 hit stores the following month at a very low price according to DigiTimes but don't have anything new to report about the release date of the Richland chips. It is nice to have low cost CPUs available on the market, but it seems odd when even the lowest priced motherboard will run you about twice as much as the CPU you will be putting on it.
"AMD plans to cut some of its APU prices at the end of April to welcome its next-generation Richland APUs, set for launch in early June, according to sources from PC players.
Prices of AMD's APUs including A8-5600K, FX-8320, FX-6300 and FX-4300 will see 8-15% drops and the CPU maker will also start shipping its A4-4000 in mid-April for sales in mid-May priced at US$40."

GTC 2013: Cortexica Vision Systems Talks About the Future of Image Recognition During the Emerging Companies Summit
Subject: General Tech, Graphics Cards | March 20, 2013 - 09:44 PM | Tim Verry
Tagged: video fingerprinting, image recognition, GTC 2013, gpgpu, cortexica, cloud computing
The Emerging Companies Summit is an series of sessions at NVIDIA's GPU Technology Conference (GTC) that gives the floor to CEOs from several up-and-coming technology startups. Earlier today, the CEO of Cortexica Vision Systems took the stage to talk briefly about the company's products and future direction, and to answer questions from a panel of industry experts.
If you tuned into NVIDIA's keynote presentation yesterday, you may have noticed the company showing off a new image recognition technology. That technology is being developed by a company called Cortexica Vision Systems. While it cannot perform facial recognition, it is capable of identifying everything else, according the company's CEO Ian McCready. Currently, Cortexica is employing a cluster of approximately 70 NVIDIA graphics cards, but it is capable of scaling beyond that. Mcready estimates that about 100 GPUs and a CPU would be required by a company like eBay, should they want to implement Cortexica's image recognition technology in-house.
The Cortexica technology uses images captured by a camera (such as the one in your smartphone), which is then sent to Cortexica's servers for processing. The GPUs in the Cortexica cluster handle the fingerprint creation task while the CPU does the actual lookup in the database of known fingerprints to either find an exact match, or return similar image results. According to Cortexica, the fingerprint creation takes only 100ms, though as more powerful GPUs make it into mobile devices, it may be possible to do the fingerprint creation on the device itself, reducing the time between taking a photo and getting relevant results back.
The image recognition technology is currently being used by Ebay Motors in the US, UK, and Germany. Cortexica hopes to find a home with many of the fashion companies that would use the technology to allow people to identify and ultimately purchase clothing they take photos of on television or in public. The technology can also perform 360-degree object recognition, identify logos that are as small as .4% of the screen, and identify videos. In the future Cortexica hopes to reduce latency, improve recognition accuracy, and add more search categories. Cortexica is also working on enabling an "always on" mobile device that will constantly be indentifying everything around it, which is both cool and a bit creepy. With mobile chips like Logan and Parker coming in the future, Cortexica hopes to be able to do on-device image recognition, which would greatly reduce latency and allow the use of the recognition technology while not connected to the internet.
The number of photos taken is growing rapidly, where as many as 10% of all photos stored "in the cloud" were taken last year alone. Even Facebook, with it's massive data centers is moving to a cold-storage approach to save money on electricity costs of storing and serving up those photos. And while some of these photos have relevant meta data, the majority of photos taken do not, and Cortexica claims that its technology can be used to get around that issue, but identifying photos as well as finding similar photos using its algorithms.

Tagged: windows rt, nvidia, GTC 2013
NVIDIA develops processors, but without an x86 license they are only able to power ARM-based operating systems. When it comes to Windows, that means Windows Phone or Windows RT. The latter segment of the market has disappointing sales according to multiple OEMs, which Microsoft blames them for, but the jolly green GPU company is not crying doomsday.
NVIDIA just skimming the Surface RT, they hope.
As reported by The Verge, NVIDIA CEO Jen-Hsun Huang was optimistic that Microsoft would eventually let Windows RT blossom. He noted how Microsoft very often "gets it right" at some point when they push an initiative. And it is true, Microsoft has a history of turning around perceived disasters across a variety of devices.
They also have a history of, as they call it, "knifing the baby."
I think there is a very real fear for some that Microsoft could consider Intel's latest offerings as good enough to stop pursuing ARM. Of course, the more the pursue ARM, the more their business model will rely upon the-interface-formerly-known-as-Metro and likely all of its certification politics. As such, I think it is safe to say that I am watching the industry teeter on a fence with a bear on one side and a pack of rabid dogs on the other. On the one hand, Microsoft jumping back to Intel would allow them to perpetuate the desktop and all of the openness it provides. On the other hand, even if they stick with Intel they likely will just kill the desktop anyway, for the sake of user confusion and the security benefits of cert. We might just have less processor manufacturers when they do that.
So it could be that NVIDIA is confident that Microsoft will push Windows RT, or it could be that NVIDIA is pushing Microsoft to continue to develop Windows RT. Frankly, I do not know which would be better... or more accurately, worse.

Efficient cooling has always and will always be a limiter on the power of processors, especially as the processes used shrink and transistor density increases. Over the years we have seen heatpipes become common and watercooling move into the mainstream with the advent of all-in-one coolers. Thermal interface material has not changed much, even though we have heard of many developments nothing has been released to market. Carbon black proved to be too long in development and might be replaced by nanotube forests though there is do it yourself thermal paste doped with diamonds that you can make right now.
From there we saw a project doping thermal paste with graphene, which could provide conductivity of up to 600 W/mK once it becomes available, hopefully in sheet form for easy installation. Increasing the thermal conductivity of your TIM is a good thing, assuming that the heatsink absorbing the heat can keep up with the transfer which is what makes the news out of FrostyTech so interesting. Researchers are sandwiching a material they call K-Core Annealed Pyrolytic Graphite in between layers of aluminium and other metals to create a heatsink with a thermal conductivity of up to 1092W/mK in certain situations. It is not as simple as doping a heatsink with this new material though, it is only efficient at moving heat horizontally. Read on to find out more at FrostyTech.
"When the thermal conductivity of copper and aluminum heat spreaders just won't cut it, the future revolves around a material called Annealed Pyrolytic Graphite. Let's consider the numbers: where a solid aluminum heat spreader has a thermal conductivity of 126W/mK, the same heatspreader with an Annealed Pyrolytic Graphite core would see thermal conductivity on the order of 1092 W/mK. That's not a typo."
